Your chance to win a pair of BTTF II Nike Air Mags

The fully-working Nike Air Mags as seen in Back to the Future II are finally becoming a reality this week.

The shoes come with self-fitting power laces and LED lights, and will only be available via a lottery system to make sure everyone has a fair chance to getting a pair - not just crazy rich people or professional flippers.

To stand a chance of winning a pair, you need to make a donation to the Michael J Fox Foundation, whish is an amazing charity raising funds for groundbreaking research into Parkinson's disease.
